I have a patch for updating Boost.Test to use the new timers, since the old one is deprecated. I'll create a ticket on trac and attach the patch later today or tomorrow for your perusal.

On a related note, progress.hpp is still includes boost/timer.hpp, so it is not currently (at least as of 1.50) possible to use the new timers and the progress display in the same compilation unit.
